Problems solved by technology

However, due to the small particle size and light weight of ultrafine dust and flour particles, they will still be suspended in the "purified" air and be sucked out, and the dust removal effect is not ideal.
For example, the patent CN10322381A discloses a cyclone dust collector, which includes a dust collector body, a heating device is provided on the outer wall of the dust collector body, and a vibration device is also provided on the outer wall and the inner wall of the dust collector body, which can effectively solve the problem of Defects of adhered materials in the dust collector, but the problem of dust removal effect has not been well resolved

Embodiment 1

[0024] like figure 1 As shown, the grain processing waste gas dust removal device of the present invention includes a cyclone dust collector body 1 and an air intake pipe 3 and an exhaust pipe 5 arranged on it, wherein the cyclone dust collector body 1 consists of a cylindrical upper section 1-2 and an inverted The lower section 1-3 in the shape of a cone is formed, and a dust discharge port 1-1 is arranged at the lower end thereof. The intake pipe 3 is located at the top of the cyclone dust collector body 1, and is connected and communicated with the upper section 1-2 along the tangential direction of the upper section 1-2 of the cyclone dust collector body 1. A booster pump 2 can be set on the intake pipe 3 to enter the cyclone dust collector. The exhaust gas in the main body 1 of the cyclone flows in a spiral shape, and the centrifugal force generated by the centrifugal force throws the larger dust particles to the area close to the inner wall of the main body 1 of the cycl...

Embodiment 2

[0026] see figure 2 , as a further improvement, a constriction 3-2 can be set near the air outlet 3-1 of the air intake pipe 3, and the atomizing nozzle 4 of the humidification mechanism is installed in the constriction 3-2 position, and the water mist is sprayed on the passing In the exhaust gas at the neck 3-2 part, in the process of rapid expansion after flowing out of the neck 3-2 with the airflow, the water mist and the exhaust gas are mixed more evenly, and all the dust in the exhaust gas is absorbed, and enters the cyclone dust collector body. 1 is the absorption of dust and impurities, which is beneficial to avoid the adhesion of dust and impurities to the inner wall of the main body 1 of the cyclone.

[0027] Implementation three

[0028] see image 3 , Further, a deflector 8 can be set at the air outlet 3-1 of the air intake pipe 3, so that the exhaust gas flows spirally close to the inner wall of the cyclone dust collector body 1, and the angle between the deflec...

Embodiment 4

[0030] see Figure 4 , Further, several swirl baffles 9 can be arranged at the lower part of the inner wall of the cyclone dust collector body 1 to reduce the speed of the swirl flow, so that the dust impurities in the swirling downward exhaust gas fall faster. The height of the swirl baffle 9 should not be too high, and can be set to 5~20mm, so that the swirl velocity in the area close to the inner wall of the cyclone dust collector body 1 is reduced without affecting the cyclone dust collector body 1. .

Abstract

The invention discloses a grain processing waste gas dust removal device, which comprises a cyclone dust remover body, an air inlet pipe and an exhaust pipe, wherein the air inlet pipe and the exhaustpipe are arranged on the cyclone dust remover body; the air inlet pipe is provided with a humidification mechanism. The dust removal device can be used for humidifying dust in waste gas, so that themass of the sundry dust is increased; the sundry dust can favorably enter the inner wall region of the cyclone dust remover body under the effect of the cyclone centrifugal force of the waste gas; thefalling speed is accelerated; the separation dust removal effect is improved.

Description

technical field [0001] The invention belongs to the technical field of exhaust gas treatment, and in particular relates to a grain processing waste gas dust removal device. Background technique [0002] Grain processing enterprises have a large scale and a wide range, and in the process of grain removal and flour processing, a large number of fine dust particles and ultra-fine flour are easily diffused in the ambient air. Although they are not poisonous, they also bring different degrees of discomfort to employees. It is suitable for hazards, so it needs to be equipped with enough dust collection and dust removal equipment to avoid pollution to the work area and the external environment. [0003] At present, the use of cyclone dust collectors is relatively common in the field of grain processing enterprises. The dust removal of cyclone dust collectors mainly uses the centrifugal force during the rotation of the inlet air in the dust collector cavity and the gravity of the du...
